In what ways are fuel cells and galvanic cells similar and in what way

1.	In what ways are fuel cells and galvanic cells similar and in what ways are they different ?
Answer» Similarity between fuel cells and galvanic cells : In both the cells, there is oxidation at anode and j reduction at cathode. The cell potential is developed due to net redox reactions. Both are galvanic cells. Difference in fuel cells and galvanic cells : Fuel cells involve electrodes with large surface area while galvanic cells involve electrodes with j compact surface area. Fuel cells involve gaseous materials on a large scale while galvanic cells involve gaseous materials at a definite pressures along with electrolytes or there may not be gases. In fuel cells, the cell potential is developed due to exothermic combustion reactions while in galvanic cell, cell potential is developed due to normal redox reactions. In fuel cells gaseous electrode materials are continuously supplied from outside while in galvanic cells electrode materials have constant concentration or may change due to reactions.
